Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near future, or even now.

Cooking devices that incorporate three-dimensional (3D) printers, lasers, or other software-driven processes may soon replace conventional cooking appliances such as ovens, stovetops, and microwaves. But will people want to use a 3D printer -- even one as beautifully designed as a high-end coffee maker -- on their kitchen counters to calibrate the exact micro- and macro-nutrients they need to stay healthy? Will 3D food printing improve the ways we nourish ourselves? What sorts of hurdles will need to be overcome to commercialize such a technology? Researchers explore the benefits and drawbacks of 3D-printed food technology, cooking 3D-printed food with lasers as part of the system, how 3D-printed food compares to the 'normal' food we eat, and the future landscape of our kitchens.

Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.

An international team has discovered how electrons can slither rapidly to-and-fro across a quantum surface when driven by external forces. The research has enabled the visualization of the motion of electrons on liquid helium.

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured experimentally. Neutrino experiments use targets that are nuclei made of many protons and neutrons bound together. This complicates interpreting those measurements to infer proton structure. By scattering neutrinos from the protons that are the nuclei of hydrogen atoms in the MINERvA detector, scientists have provided the first measurements of this structure with neutrinos using unbound protons.

Additive manufacturing of food involves designing, pre-processing, manufacturing, and post-processing, and each step is an opportunity to create innovative foods. Researchers identify factors that affect the print quality and shape complexity of the food created. For example, changing the printing patterns and ingredients of the initial mix or paste can affect the food's matrix and microstructures and therefore its texture. Accounting for these features can increase food quality, improve control, and speed up printing.

Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.

Two researchers have used a standard laptop computer and a humble piece of rock -- from the 'waste pile' of a diamond mine -- to solve a long-held geological conundrum about how diamonds formed in the deep roots of the earth's ancient continents.

When exotic species such as parrots, snakes, monkeys, or aquarium fishes are kept as pets, this may lead to unsustainable trade and impact negatively the conservation of these species globally. Understanding what drives demand among keepers may help inform adequate conservation strategies to address unsustainable trade.

In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.

The elimination of daylight-saving time is a frequently -- and heatedly -- discussed topic. Often, only the aspect of electricity consumption due to artificial lighting is considered. In a new study, researchers have now analyzed whether daylight saving also has an impact on the heating and cooling energy required for office buildings, and what role climate change might play in this. The results should delight supporters of daylight-saving time.

Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.
